About this product
The Mossberg 835 Ulti-Mag Combo is a pump-action 12-gauge shotgun sold with two interchangeable barrels — a 24-inch barrel for turkey hunting and a 28-inch vent-rib barrel for waterfowl and general wingshooting — both finished in Mossy Oak Break-Up Country camo over a synthetic stock. The "combo" format is aimed at hunters who want one receiver to cover two distinct hunting seasons instead of buying two separate shotguns.
Why does this shotgun come with two barrels?
The 24-inch barrel is set up with adjustable fiber optic sights and an Ulti-Full turkey choke for tight, long-range patterns on a turkey's head and neck. The 28-inch vent-rib barrel adds a fiber optic front sight and comes with an Accu-Mag choke set for broader pattern control across waterfowl and clay/upland use. Swapping barrels on the same action lets one shotgun cover both roles without buying and storing two separate guns.
What makes the 835 chambering different from a standard 12-gauge pump?
The 835 Ulti-Mag is built around a 3.5-inch chamber, meaning it can run 2¾-inch, 3-inch, and 3.5-inch 12-gauge shells, including the heaviest magnum turkey and waterfowl loads on the market. Mossberg also over-bores the barrels to 10-gauge internal dimensions for their full length, which is designed to reduce pellet deformation and tighten shot patterns compared to a standard-bore 12-gauge barrel.
What's the capacity and action type?
It's a pump-action shotgun with a tube magazine holding roughly 5+1 rounds depending on shell length, along with dual extractors, twin action bars, and an anti-jam elevator — mechanical features aimed at reliable cycling with mixed shell lengths in the field.
How does delivery work for a shotgun purchase?
As a firearm, the 835 Ulti-Mag Combo ships to a licensed FFL dealer for pickup, not to your home address, where you'll complete a background check and the standard transfer paperwork.
Mossberg's 835 Ulti-Mag line has been in production for decades specifically because the 3.5-inch-chamber, over-bored-barrel formula keeps proving popular with hunters who want one gun capable of handling both light target loads and full magnum turkey or waterfowl shells without a felt-recoil penalty that would come from a smaller, lighter action trying to do the same job. Swapping between the two included barrels takes only a few minutes and requires no tools beyond what's needed to open the action, since both barrels are built to the same receiver interface. Choke tubes are interchangeable within each barrel's thread pattern, so hunters who want a different constriction than the included Ulti-Full or Accu-Mag set can typically find aftermarket options for both the 24-inch and 28-inch barrels.
At roughly 7.5 pounds and about 44.75 inches overall with the 28-inch barrel installed, this is a purpose-built hunting shotgun rather than a home-defense gun, and the two-barrel combo setup is the main reason to pick this over a single-barrel 835. Mossberg has produced the 835 platform long enough that replacement parts, extra barrels, and accessories remain widely available, which matters for a hunting gun expected to stay in service across many seasons. Recoil management is worth planning for with full 3.5-inch magnum loads, since heavy turkey and waterfowl shells generate substantial felt recoil in a gun this weight — a slip-on recoil pad is a common, inexpensive addition for hunters who shoot a lot of magnum ammunition through their 835 and want to reduce shoulder fatigue over a long day in the blind.
FFL transfer required
This item is a firearm and ships only to a licensed FFL dealer, never to a home address. At checkout, enter your preferred dealer as the shipping address, or leave it blank and we will assign a licensed dealer near you at no extra cost.
